Solved

Hello community! Going to say thanks in advance for your help and direction here. Before I get started, understand that I am using an external rotary encoder knob as the user input for the display, no touchscreen. I am hijacking the button pressed/released behavior to show the navigation with the encoder and manually handling the encoder press to load a new screen or other behavior as needed. I have the external hardware mapped in properly and can view the knob turn/press events as needed, no problems there.I'm trying to build in a menu list of sorts with each menu entry as flex button with some custom behavior. I want for each entry to have an icon, a text label, and a different pressed/released background image, but I only want to have the icon showing when the menu entry is selected. When the entry is not selected, the background image will match the overall UI background to blend in. See the image below where the first entry is selected.This same menu entry behavior will ultimately

Hello,I've recently been using Thread application examples like "Thread_FTD_Coap_Multicast", but when I tried adding other features such as ADC, I encountered errors due to redundancy caused by too many files.I'm wondering how to start a new clean project with STM32CubeMX and then incorporate the Thread protocol afterwards.Have you ever done this? If so, do you have any suggestions?Thank you.

I use a VL53l1X looking trough a oil layer of ca. 20 mm. When getting measured distance 3 times with GetResult(), it returns (example):Status = 0, dist = 11, Ambient = 16, Signal = 20936, #ofSpads = 6Status = 0, dist = 19, Ambient = 8, Signal = 18104, #ofSpads = 6Status = 0, dist = 38, Ambient = 16, Signal = 15864, #ofSpads = 19 --> some 'magic' automatic changed the NrOfSpads from 6 to 19, which also affects the measured distance. When I set the NrOfSpads with VL53L1X_Status_t VL53L1X_SetROI(uint16_t X, uint16_t Y);, this only limits the maximal used NrOfSpads, but it's further possible that the sensor switches to a lower NrOfSpads autonomous. How can I force the sensor to use a defined NrOfSpads?

Hello everyone,I intend to migrate an LPC development to the new stm32h5 family, I find the versatility that its flash offers very interesting. Being able to separate a set of memory into two blocks to run the main program without the need for an IAP firmware. but I have doubts.In my old LPC I had an EEPROM memory clearly separated from the memory block. In the new stm32h5 there is talk of a high-cycling Flash capability that can function as a kind of EEPROM. My question is, can I dedicate the bank 1 portion of the Flash to EEPROM emulation and still maintain the ability to swap between banks for software updates?Thanks in advance!Victor

Using the STM32H747I-DISCO, I am having problems getting SPI working at all.I am using SPI5, to allow connecting an X-NUCLEO-NFC08A1 directly via the Arduino headers.I do not see any data on the SCK line and HAL_SPI_Transmit() always fails.Looking in stm32h7xx_hal_spi.c, I see that SPI_FLAG_EOT is never detected and so HAL_SPI_Transmit() times out with HAL_SPI_ERROR_FLAG set.Is there a working sample showing SPI configuration and use on the STM32H747?Can anyone suggest what I'm doing wrong?Thanks.Pin/port definitions:#define SPIx SPI5 #define SPIx_IRQn SPI5_IRQn #define SPIx_SCK_GPIO_CLK_ENABLE() __HAL_RCC_GPIOK_CLK_ENABLE() #define SPIx_MISO_GPIO_CLK_ENABLE() __HAL_RCC_GPIOJ_CLK_ENABLE() #define SPIx_MOSI_GPIO_CLK_ENABLE() __HAL_RCC_GPIOJ_CLK_ENABLE() #define SPIx_CLK_ENABLE() __HAL_RCC_SPI5_CLK_ENABLE() #define SPIx_SCK_PIN 0 #define SPIx_SCK_GPIO_PORT GPIOK #define SPIx_SCK_AF GPIO_AF5_SPI5 #define SPIx_MISO_PIN 10 #define SPIx_MISO_GPIO_PORT GPIOJ #define SPIx_MISO_AF GPIO_AF5_SPI5

Hi @Rene Lenerve  @JL. Lebon  @Brian TIDAL So basically I am connecting ST25DV64KC tag with MKE14F512VLL16 based controller and I want to write on the tag through i2c but as I am sending data using I2c write and as I am checking using Logic analyzer it showing its writing and sending ack but when I am checking using st nfc tap app  options read memory  there nothing was written can you guys confirm few things like is tag slave  device address  is 0xA6  for writing on tag and is it mandatory to give memory address or it will assume 0000h as base address and write on it  and to write on tag do we need to send one byte at a time .Can you please provide details about i2c communication to  write on tag by the way I have already gone through the datasheet.

Hi @Khouloud ZEMMELI I generated C code and other files after opening .IOC file in STM32CubeIDE (not STM32CubeMX).I observe many FLASH sections in the STM32H753BITX_FLASH.ld file do not call ALIGN(4).The left side file is the one that got generated after generating code, where is the right side file is the one that I have received from my colleague.I hereby request that STM32CubeMX be updated to include the ALIGN(4) wherever necessary.Regards,Rajeev 

Hello,I recently purchased the STM32U5G9J-DK2, on the pre-loaded demo there is a map view which takes advantage of the vector graphics acceleration.The demo is "TouchGFX Demo 7", but the version available in Designer v4.23.0 is missing the map screen.Is the TouchGFX project / source code available for this demo with the added map?Many Thanks,Ant 

I can't find the page size of STM32401RE nucleo flash memory in the reference manual. Does anyone have the information?Thanks

Hi all,I am designing an application on a STM32L431. I need to consume the least amount of power. The MCU will have to use the CAN module both in transmit and receive mode. The reference manual does not give too much details on how the lower power mode work with each of the peripherals. For example, if I set the device in low-power sleep mode and I receive a CAN message, it will wake up the CPU clock and main loop restart? Can I set the Tx mailboxes of the CAN buffer and immediately send the device in low-power sleep mode? The CAN message will be sent anyway?  

HiI have an imported project and I would like to modificy the GPIO configuration inside board.cI saw board.c is a file generated from pinMapEditor configuration but is I open the project and the PinMapEditor page I'm not able to modify anything because the pin configuration setting does not open and clicking on the pin name does nothing happen.Any suggestion?ThanksFabio  

Hello everyone,we are developing a product using STM32F413.We got a new requirement, that the chip needs to activate ROP level 1. We want to do this from firmware code, if possible.I noticed that after flashing my firmware and running the code that activates the ROP, the mcu stops working until i perform a power on reset. The ROP is set to level 1 after the power on reset, as expected. The need for the power on reset seems to be caused by not having a power on reset between using the programmer and setting the ROP level. Problem is, that we have a huge super-cap on the board, buffering the power, so a power on reset is out of the picture for production.I know that for STM32L0x3, there was a way around this by performing a wakeup from standby instead of a POR. I had no luck implementing the same for STM32F413. Is there any way to set the ROP from a just flashed firmware without doing a power on reset? From RM0367 Rev8 chapter 3.4 (stm32l0x3 ref manual):im in the situation described

Hi,I have the following board : NUCLEO-F429ZIThe datasheet says that UART3 is the STLINK UART that can be used over USB.I configured this UART but when I try to receive anything from the terminal that is connected to the UART com port, I don't see the interrupt being triggered.The objective is to receive some data over UART3, process it, and send the processed data over UART6.UART3 init in main.c/** * @brief USART3 Initialization Function * @PAram None * @retval None */ static void MX_USART3_UART_Init(void) { /* USER CODE BEGIN USART3_Init 0 */ /* USER CODE END USART3_Init 0 */ /* USER CODE BEGIN USART3_Init 1 */ /* USER CODE END USART3_Init 1 */ huart3.Instance = USART3; huart3.Init.BaudRate = 115200; huart3.Init.WordLength = UART_WORDLENGTH_8B; huart3.Init.StopBits = UART_STOPBITS_1; huart3.Init.Parity = UART_PARITY_NONE; huart3.Init.Mode = UART_MODE_TX_RX; huart3.Init.HwFlowCtl = UART_HWCONTROL_NONE; huart3.Init.OverSampling = UART_OVERSAMPLING_16; if (HAL_

I have a NUCLEO-H723ZG.From the STM32 examples, in the LwIP_UDP_Echo_Server/STM32CubeIDE/STM32H723ZGTX_FLASH.ld file, we have: .lwip_sec (NOLOAD) : { . = ABSOLUTE(0x30000000); *(.RxDecripSection) . = ABSOLUTE(0x30000200); *(.TxDecripSection) . = ABSOLUTE(0x30000400); *(.Rx_PoolSection) } >RAM_D2 AT> ROM   However, when creating a project with STM32CubeIDE 1.13.1, We don't get to set the Rx_PoolSection.

I have a PCA with a blown TVS. The markings are: ST e3 G3BA◇YZ521I've seen TVS datasheets with markings starting with 3BA, but the diamond symbol is throwing me off. Can you assist?

In an STM32F427, according to the Backup domain reset subchapter of RCC chapter of RM0090rev.19, backup domain can be reset by setting RCC_BDCR.BDRST. There is no other condition to this mentioned in that subchapter nor elsewhere in related material (e.g. in description of RCC_BDCR.BDRST bit) in the RM.However, experimentally I found, that backup domain reset does not happen after setting RCC_BDCR.BDRST, if PWR_CR.DBP is not set.JW

Hi STM Team,We are using VL53L0CXV0DH Sensor for our Object Detection Application in Medical Field. The Sensor is working fine, but after 1 month of time the dust in the environment covers the sensor's LED part, so, the dust was affected the overall sensor performance.We already tried some dust protective films, but that was created the sensor to detect the object wrongly or always detects objects.Kindly provide any protective covers/films or any suggestions to cover the sensor from environmental dusty particles as well as not absorbing the sensor rays.   

Hi,I am using stm32cubeIDE to use USB OTG/Dual_role but it does not generate the middleware! I do appreciate any helpThanks

We are using SPC58NH-disp.We are developing a software that we want to print the data we receive over CAN-FD to the screen with TCP.We are using a Simple TCP Echo Server Demo for TCP.Data flow takes place indefinitely and in indefinite numbers.But suddenly the device is locked.Either, Can-fd data is transmitted endlessly when the Ethernet socket is not plugged in.However, when the socket is inserted, the device is locked even if the connection is not established.Can you help with this crash?

  Hi I followed this yt-guide for CAN-bus https://www.youtube.com/watch?v=JfWlIY0zAIc&t=918s I'm however using a different type of nucleo board (L433RC-P in my case and F103C8tx in the video) and a different type of CAN-transceiver (MCP2561T-E/SN vs MCP2551 in the video). My board uses a different type of can periphery (can1 vs can). My solution to this difference was to just change all of the code where he writes can to can1. Yet checking with an oscilloscope, I don't seem to be sending any CAN signal. relevant code: Setup:      

I am currently facing an issue with the RPM readings while running a motor using the STEVAL-IPM10B and NUCLEO-F302R8 in conjunction with the ST Motor Control Workbench.Upon measurement with a tachometer, I observed a difference between the practical RPM values and the readings displayed on the dashboard. Even though I utilized the Motor Profiler to generate motor parameters.I had attached the Program files for your reference.Thanks in Advance. 

Hi,My thread starts working with the features I mentioned below:    panID = 0x2222U; channelNB = 12U; networkKey = (otNetworkKey) { .m8 = {0x00, 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88, 0x99, 0xAA, 0xBB, 0xCC, 0xDD, 0xEE, 0xFF} };    I want to change this config in mcu working. How can I do this? I changed my values and I tried the code below:    otError error; error = otLinkSetChannel(NULL, channelNB); if (error != OT_ERROR_NONE) { return AKUS_ERROR; } error = otLinkSetPanId(NULL, panID); if (error != OT_ERROR_NONE) { return AKUS_ERROR; } otNetworkKey *ptr_key = (otNetworkKey*)&(networkKey); error = otThreadSetNetworkKey(NULL, ptr_key); if (error != OT_ERROR_NONE) { return AKUS_ERROR; }   but my thread app fails when I use this codes.Best regards.

I am currently encountering an issue while configuring the Motor Control Workbench. Upon completion of the configuration, I receive an error stating "ST Intranet Updater Server is unknown: mcucrossselector.codex.cro.st.com." Additionally, the compilation process in Motor Control Workbench results in "Compiled with errors."I am using STM32 Cube IDE to upload the program. Could you please provide guidance on whether this server error is something that needs attention, or if it can be neglected?Thanks in Advance
